<div class="textblock"><p>Encapsulated class to read JSON metadata into memory, and write the JSON metadata for each node. </p>
<p>This class encapsulates the outofcore node metadata serialization/deserialization. At the time it was written, this depended on <a class="el" href="structc_j_s_o_n.html">cJSON</a> to write JSON objects to disk. This class can be extended to have arbitrary ascii metadata fields saved to the metadata object file on disk.</p>
<p>The JSON file is formatted in the following way: </p><pre class="fragment">{
  "version": 3,
  "bb_min":  [xxx,yyy,zzz],
  "bb_max":  [xxx,yyy,zzz],
  "bin":     "path_to_data.pcd"
}
</pre><p>Any properties not stored in the metadata file are computed when the file is loaded (e.g. <a class="el" href="classpcl_1_1outofcore_1_1_outofcore_octree_node_metadata.html#a359b0df3a9e828b2a51d68fe50e9ea80">midpoint_xyz_</a>). By convention, the JSON files are stored on disk with .oct_idx extension.</p>
